I don't believe it's for the rich and famous or the purbred breeders only. More and more commercial operations are using it. With the ability to synch cattle for timed breeding, it's easier than ever. There are several benefits, if you are willing to go the extra mile to make it work. Some articles on using AI in a commercial herd:
From CattleToday:
"The big question, remains though; "Can these benefits justify the costs of AI?" Recent studies conducted by a number of university and industry researchers suggest that they can, depending on the individual producer's situation. It is also noteworthy that as the beef industry becomes increasingly product and consumer oriented and the national animal identification system is implemented, genetic background will take on greater importance. This may be one of the greatest driving forces for increased use of AI. Also, customers "downstream" from the cow-calf sector (feedyards, packers, etc.) may become familiar with the top AI sires and place added value on their calves."

From University of MN, Grand Rapids.
"The use of artificial insemination (AI) is one of the most effective methods to enhance the profitability of most beef cattle production systems."

"If pregnancy rate was held constant, ESAI's cost per pregnancy exceeded natural service, especially for smaller herds. But if the costs were adjusted for the expected increase in calf weaning weight resulting from ESAI, cost of pregnancy was lower to produce a 500-lb. equivalent weaned calf with ESAI."

"More and more beef producers are using artifical insemination (AI) sires in order to increase profit."

"But it's the long-term issues that really start to make the case for AI. Those include the opportunity for rapid and accurate genetic improvement. "The main reason to AI is for genetic improvement," DeGroff says. "A producer has more control over what actually ends up in the calf crop. The accuracy of EPDs is better on semen than bulls. And producers can afford semen that came from a bull they couldn't afford to own."
